Key Takeaways
- Shares of Onsemi declined 9% Wednesday following an underwhelming Investor Day presentation.
- The semiconductor maker introduced its Embedded Power Platform, boasting 3-5x greater power density compared to existing technologies.
- Subaru has become an early adoption partner, evaluating the technology for upcoming electric vehicle designs.
- Federal Reserve interest rate increases compounded selling pressure, as elevated borrowing costs impact EV and industrial equipment demand.
- Year-to-date, ON shares maintain a 23% gain, outperforming the Nasdaq’s 12% increase.
Shares of Onsemi retreated 9% Wednesday, settling at $66.60, as the company’s highly anticipated Investor Day presentation left market participants underwhelmed.
ON Semiconductor Corporation, ON
The Arizona-headquartered semiconductor manufacturer showcased its latest innovationāthe Embedded Power Platformārepresenting a wafer-level design methodology that consolidates multiple semiconductor components into one unified silicon device.
According to company specifications, this platform achieves three to five times greater power density relative to traditional solutions, with performance varying by use case.
The technology diverges from standard approaches by utilizing the silicon wafer as the structural foundation itself, enabling integration of silicon, silicon carbide, and gallium nitride materials within a unified framework.
“The industry has long maintained a separation between the semiconductor die and its packaging. EPP fundamentally reimagines this by incorporating the silicon directly into the system design,” explained CEO Hassane El-Khoury.
Japanese automaker Subaru Corporation has partnered with Onsemi as an initial development collaborator, testing the platform’s capabilities for next-generation electric vehicle systems. The partnership grants Subaru priority access to prototype samples, simulation frameworks, and engineering consultation.
Performance Specifications and Target Markets
Within automotive implementations, the company reports the platform achieves up to four times enhanced power density alongside 15% reduced energy losses versus traditional methodologies.
In artificial intelligence infrastructure applications, a prototype solid-state circuit breaker utilizing the platform demonstrated approximately 50% size reduction and operated 20% cooler than conventional alternatives.
Onsemi is positioning the technology toward automotive, industrial, and AI data center sectors. The company indicates the platform could compress product development timelines to just four months.
Initial sampling distribution to key customers is scheduled for 2026.
Federal Reserve Policy Intensified Downward Pressure
The Federal Reserve’s interest rate increase Wednesday further pressured the stock. Elevated financing costs typically dampen consumer and business appetite for electric vehicles and industrial machineryāsegments representing the majority of Onsemi’s revenue streams.
The stock experienced accelerated declines following the Fed announcement, amplifying the negative sentiment from the Investor Day event.
Notwithstanding Wednesday’s downturn, ON shares have advanced 23% year-to-date. This performance surpasses the Nasdaq composite, which has gained 12% during the identical timeframe.
In its most recent quarterly report, Onsemi delivered earnings results exceeding Wall Street forecasts and elevated its revenue projections for AI data center business, providing temporary support for the stock.
The Embedded Power Platform leverages Onsemi’s established 12-inch silicon wafer fabrication facilities, eliminating the requirement for completely new manufacturing infrastructure to achieve production scale.
Distribution of EPP evaluation samples to strategic customers and ecosystem collaborators throughout automotive and AI sectors is planned for late 2026.
